The DW_axi_x2p is an AXI-to-APB bridge that allows the connection of an APB slave to AXI. APB components attached to the DW_axi_x2p can be either AMBA 2 APB or AMBA 3 APB-compliant. In other words, they can include either or both of the signals, pready and pslverr, added by the AMBA 3 APB protocol.

One side of the DW_axi_x2p is an AXI slave interface, which accepts reads and writes from an attached AXI master interface. The other side is an APB 3 master interface, which provides reads and writes to attached APB components. The DW_axi_x2p is a configurable component, allowing the IP integrator to optimize the IP to suit specific design requirements.
